Do you know how to find the orbital velocity for the object?
Do you know how to find the escape velocity for the object?
What's the difference?

The orbital velocity is jusr rdø/dt, while the escape velocity, for a stationary object shot vertically in a gravitational field, would be v=(MG/r)^1/2, where M is the mass of the planet or whatever the object is stationary on.

First off, your escape velocity equation is incorrect (and it doesn't have to be the vertical direction)
